First, We are a victim of fraud and scam and are distressed since day one and loss of thousands of dollars. After searching and reviews, we bought a 2015 Lexus RX350 for family use from a seller who had owned this vehicle for over five years but the seller never disclosed and represented in the sale of this vehicle that It was rebuilt and had engine front cover timing gasket leak! They said it was clean title and didn-??t have any issues. Plus the blind spot sensors had issues. The same day these problems were recovered after we bought it and from the same first day we tried to return the vehicle and used all other option legally from day one till now to resolve it with the seller, but they didn-??t want to resolve neither return it or fix the problems with vehicle but they kept denying. Vehicle been sitting in parking lot since the first day of bought and never able to register and it-??s been over 8 months. Also found out, these year models like mine 2015 RX350 timing cover leak were common problem back then. I-??m desperately asking to issue a fix remedy by Lexus or Toyota therefore, please help with this.. thanks in advance!

Engine cut out suddenly while driving 45 MPH, followed by Battery Light, Check Engine Light, and Power Steering Light forcing hazardous emergency stop. Engine would no longer crank, and car had to be towed to nearest Lexus Certified Repair Facility. Technician scanned the system and found four Codes: P0335, P1603, P1604, P1605. After bore-scoping front three cylinders, technician tried to turn motor by hand and was unable to. The motor turned in reverse, but not forward. Technician removed oil pan to find pieces of valve spring broken and pieces of the piston rings and piston fragments from one of the rear three cylinders. Motor will need to be replaced or completely rebuilt after only 133,458 miles and regular servicing.

It has the same engine failure problem as the recall for 2022 and 2023 vehicles. The engine just stalls when it wants with no check engine light or error codes. Then restarts just fine when put in park. Lexus repair could not even find a issue. Have documents to prove it.

Engine abruptly stops and I have a 3 second stall, then the car resumes normal operation. Could be a real serious accident without warning. This happened in motion on a highway from a stop light or stop sign or pulling out onto traffic.

The push-button (keyless entry) ignition did not kill the motor. My car engine ran from approximately 6 P.M. in an enclosed garage directly below my bedroom. At 4:30 a.M. I was awakened by my carbon monoxide detector. The entire house was filled with toxic fumes. First responders to my 911 call said the detector definitely saved my life. I was a little dizzy and had a headache but was ok after awhile. It took nearly 3 hours for the first responders' CO2 monitor to show safe air throughout my house. I have since learned that many people have died or suffered brain damage under the same circumstances, and dozens of people have told me that they experienced similar failures to shut down the engine. Fortunately, their cars were not in garages when it happened to them.

Gas tank needed to be replaced because gasoline overflowed into the fuel tank canister. Since replacement can intermittenly smell gas but dealership service department cannot smell unexplained excessive engine noise in whicc dealership cannot hear, and cannot maintain an alignment.

On Feb 9 2016 a rodent had chew the wires inside my engine which the battery/check engine and the all wheel traction light came on. So I drove it to the dealer ship in Tacoma fife of wa. So my insurance company told them to replace the whole engine main wiring harness for a total cost of $5372.38. Everything was good to go, then on 9 April 2016 my check engine and AWD drive traction light came on. So I took it to the dealer again, but while driving on the highway I heard chimes going off then all of a sudden it loss acceleration power and loss speed quickly. I was able to manuever off safely to the side out of traffic and down an exit to a complete stop. I turn off the vehicle and started it back on. Then I was able to drive it with a wing on a prayer and made it to the dealer shop safely im glad that I did without getting into an accident. I was told by that dealer that diagnostics found inconsistency report from there computer findings and was told the service manager will keep it to drive it for a couple of days to make sure they can catch the problem. Right now im really concern for my safety, especially it is my wife's car, and if she was driving she would not know how to react in a situation like this. So bottom line im really concern of myself, wife and family safety and need to address this because it can happen again. Please advise on how to move forward. Safety has no quitting time, I bought a Lexus becuase of its high safety expectations, but it aint working for me.

My car caught fire on its own. I was awaken by the police who said that my parked car is on fire. The fire department and police confirmed that the fire started on its own from the engine and there is no larceny. They mentioned that there was a vehicle recall for the same problem and then I search online and found the recall.
